   Abstract 

Background: Hysterosalpingography (HSG) is radiographic evaluation of uterine cavity and tubal patency. Aims: The aim of this study was to evaluate the safety and utilisation of HSG in female genital tuberculosis (FGTB) with infertility. Settings and Design: The study was conducted in a tertiary referral centre of North India. Materials and Methods: It was a prospective study on 87 cases of FGTB with infertility. Diagnosis of FGTB was made by composite reference standard using the presence of acid-fast bacilli on microscopy/culture or positive GeneXpert, positive polymerase chain reaction or epithelioid granuloma on endometrial biopsy or definitive or probable findings on laparoscopy or hysteroscopy. Statistical Analysis Used: Suitable statistical methods were used with STATA software version 12.0. Results: HSG findings were normal in 49 (56.32%) cases. There were filling defects in 14 (16.09%), short and shrunken cavity in 4 (4.49%), intrauterine synechiae in 14 (16.09%), T-shaped cavity in 3 (3.44%) and deformed uterine cavity in 5 (5.74%) cases. Fallopian tube findings were hydrosalpinx in 12 (13.79%) and 11 (12.64%) cases, beading of tube in 4 (4.59%) and 2 (2.29%) cases, pipestem appearance in 2 (2.29%) cases each and Maltese cross appearance in 3 (3.44%) and 2 (2.29%) cases, respectively. Tubal blockage was seen in 69 (79.31%) and 67 (77.01%) cases being cornual block in 28 (32.18%) and 26 (29.88%) cases, mid-tubal block in 16 (18.39%) and 15 (17.24%) cases, multiple blocks in 10 (11.49%) and 12 (13.79%) cases and fimbrial block in 15 (17.24%) and 14 (16.09%) cases. None of the cases had flare-up of the disease after HSG in the current study. Conclusion: HSG is a useful modality in FGTB with infertility.

   Introduction Top


Infertility affects 10%–15% of couples causing serious social and psychological issues and financial burden.[1],[2] Various causes of infertility include hypothalamic, pituitary, ovarian, tubal and endometrial causes.[1],[2],[3],[4],[5] Tubal factors are responsible for up to 30%–40% of cases in some studies.[3] Fallopian tubes are vulnerable to infections such as acute and chronic pelvic inflammatory diseases including tuberculosis (TB), endometriosis and past surgeries.[1] Tubal patency is an important test for subfertility which can be assessed by hysterosalpingography (HSG), sonosalpingography and laparoscopic dye test.[1],[3],[4],[5],[6],[7] HSG includes instillation of oil-based or water-based contrast medium into endometrial cavity followed by radiography to evaluate uterine cavity and tubal patency.[8],[9] There is a therapeutic effect of HSG contrast medium in subfertile women with an increase in pregnancy rate which is considerably more with oil-based contrast medium than water-based contrast medium.[8] However, recent studies indicate that much safer water-based contrast medium-based HSG is also associated with increased pregnancy rate.[9],[10] Female genital TB (FGTB) can cause subfertility through tubal blockage, endometrial atrophy and synechiae (Asherman's syndrome) and ovarian causes.[11],[12]

The present study was conducted to evaluate the role of HSG in FGTB to detect endometrial and tubal disease.


   Materials and Methods Top


It was a prospective cohort study conducted on 87 patients out of 167 women with infertility diagnosed to have FGTB on composite reference standard (CRS) as per [Appendix 1] over a 4-year study period (January 2015–March 2019) in whom HSG was done before suspicion of TB as infertility protocol. The Ethical clearance was taken from the Institute Ethical Committee, Vide No: Z-28015/44/2015. The study setting was in a tertiary referral centre. The study was carried out in compliance with the ethical principles of the Declaration of Helsinki. No sample size calculation was performed.



The inclusion criteria were cases of FGTB diagnosed on CRS who had HSG done for their infertility for tubal patency. The exclusion criteria were frank TB diagnosed before HSG or patient refused for HSG. Informed written consent was taken from all subjects. History taking, clinical examination and baseline investigations were performed. Endometrial sampling was taken in all patients in secretory phase (days 21–23) with no. 4 Karman's cannula for acid-fast bacilli (AFB) on microscopy, culture, polymerase chain reaction (and in-house DNA PCR in which a 240-bp region of the mpt64 gene was amplified by PCR) and GeneXpert and for histological type of endometrium and for any epithelioid granulomatous endometritis. Diagnostic laparoscopy with or without hysteroscopy was performed in majority of the cases for findings of FGTB which included definite findings such as beaded tubes, caseous nodules, tubercles, abdominal and pelvic adhesions, hydrosalpinx, pyosalpinx, shaggy areas and probable findings such as convoluted tubes, hyperaemic tubes and straw-coloured fluid. HSG was not routinely done in cases of FGTB for fear of flare-up of the disease but was done in 87 cases before diagnosis of FGTB as part of infertility protocol and its findings in endometrial cavity and tubes were observed in all cases. All subjects of FGTB were treated free of cost in directly observed treatment short-course centres daily.

Statistical analysis

Data analysis was carried out using STATA software version 12.0 STATA Corp 2011, Texas, USA Continuous variables were tested using Kolmogorov–Smirnov test and comparison of two groups means were tested using Student's 't' independent test. Percentage values and comparison were tested using Chi-square/Fisher's exact test. Diagnostic accuracy between CRS and the tests such as GeneXpert and PCR, sensitivity, specificity, positive predictive value, negative predictive value, LR (+) and LR (−) were calculated using 95% confidence intervals.

[Table 3] shows various diagnostic modalities used for diagnosis of FGTB with some patients having more than one finding. Pre-menstrual endometrial biopsy was done in all the cases while peritoneal biopsy was done in only 15 cases. Positive AFB on microscopy and culture of endometrium biopsy was seen in 1 (1.14%) and 3 (3.44%) cases, respectively, while in only 1 (1.14%) in peritoneal biopsy group. Positive GeneXpert was seen in 4 (4.59%) and 0 case, respectively. Positive PCR was seen in 65 (74.71%) cases of endometrial biopsy. Positive epithelioid granuloma or granulomatous endometritis was seen in 14 (16.09%) cases in endometrial biopsy and 2 (2.29%) cases of peritoneal biopsy. Definite findings of FGTB (beaded tubes, caseous nodules or tubercles) were seen in 42 (48.27%) cases while probable findings were seen in 45 (51.72%) cases while positive findings of FGTB were seen in 38 (43.67%) cases on hysteroscopy.

[Table 4] shows endometrial findings on HSG [Figure 1], [Figure 2], [Figure 3], [Figure 4], [Figure 5], [Figure 6], [Figure 7]. Normal endometrial cavity was seen in 49 (56.32%) cases. A total of 2 (2.29%) cases each showed inability to perform HSG due to constricted cervix and non-visualisation of endometrial cavity. There was irregularity of endometrium in 15 (17.24%), filling defects in 14 (16.09%) [Figure 1], [Figure 5] and [Figure 7], short and shrunken cavity in 4 (4.59%) [Figure 6], intrauterine synechiae in 14 (16.09%), T-shaped cavity in 3 (3.44%) and deformed uterine cavity in 5 (5.74%) cases. Incidental findings were unicornuate uterus in 1 (1.14%) case, arcuate uterus in 1 (1.14%) and submucosal fibroid in 1 (1.14%) case. Some patients had more than one finding.

Intravasation of dye into lymphatics and vessels in 13 (14.94%) and 12 (13.79%) cases, respectively [Figure 2] and [Figure 7]. There was no significant difference in findings in two tubes. Tubal patency was seen in 18 (20.68%) and 20 (22.98%) cases on right and left sides, respectively, while tubal blockage was seen in 69 (79.31%) and 67 (77.01%) cases being cornual block in 28 (32.18%) and 26 (29.88%) cases [Figure 3] and [Figure 5], mid-tubal block in 16 (18.39%) and 15 (17.24%) cases [Figure 4] and [Figure 6], multiple blocks in 10 (11.49%) and 12 (13.79%) cases and fimbrial block in 15 (17.24%) and 14 (16.09%) cases [Figure 7], respectively. Many patients had more than one finding. None of the patients had flare-up of TB following HSG in the present study.

All patients were given anti-tubercular therapy for 6 months, and poor prognosis of fertility was explained to them.

A total of 4 (4.59%) patients had exacerbation of TB after HSG with fever, malaise, lower abdominal and pelvic pain and excessive vaginal discharge with pelvic tenderness on bimanual examination. They were admitted for 1–2 days and were given conservative management in terms of intravenous fluids and broad-spectrum antibiotics and analgesics. All of them recovered in 2–3 days and were discharged home. None of the patients required any laparoscopy or laparotomy.


   Discussion Top


HSG is radiographic visualisation of uterine cavity and fallopian tubes after injecting a radio-opaque contrasting medium into uterine cavity through the cervix.[9] It is usually the first investigation for tubal patency being easily available even at small centres and remote places and is very economical and does not need anaesthesia.[1],[6] Laparoscopy and dye test, though gives direct depiction of the peritoneal cavity, requires general anaesthesia, expensive equipment and expertise and is available only at bigger hospitals and is usually used after tubal blockage is detected on HSG.[13],[14],[15] HSG, especially with the use of oil-based contrast medium, has some therapeutic roles in increasing pregnancy rates.[8],[9],[10]

HSG is generally avoided in suspected FGTB, especially active disease to avoid flare-up of the disease, but is often preferred as part of infertility protocol in unsuspected indolent cases of FGTB and can detect uterine and tubal disease.[6],[11],[12] In endometrial findings, HSG detected filling defects and intrauterine synechiae in 16.09% of cases, T-shaped cavity in 3.44% of cases and deformed uterine cavity in 5.74% of cases in the present study. These results were similar to the findings of Chavhan et al.[6] who observed filling defects and intra-uterine synechiae, distorted and T-shaped cavity in their study.[6]

Various tubal findings in the present study were hydrosalpinx, beaded tubes, pipestem appearance, Maltese cross appearance, intravasation of dye and tubal blocks. Chavhan et al.[6] observed tubal calcification, beading, salpingitis isthmica nodosa, rigid pipestem appearance, cornual, mid-tubal and fimbrial blocks on HSG in FGTB.[6] Eng et al.[16] and Kumar et al.[17] described calcific lymph nodes, tubal obstruction, ragged tubes, stem pipe tubes, golf club appearance, rosette tubes, leopard skin appearance and tobacco pouch appearance on HSG in FGTB.[16],[17] Farrokh et al.[18] detected irregular cavity, filling defects, T-shaped cavity, small shrunken cavity and synechiae on HSG in FGTB in their study.[18] In a study of HSG in FGTB from Iran, Ahmadi et al.[19] observed beaded tubes, golf club tube, pipestem tube, cobblestone tube, T-shaped cavity, pseudo-unicornuate uterus and collar stud abscess.[19] Shah et al.[20] also detected calcified tubes, Asherman's syndrome, irregular endometrial cavity, pseudo-unicornuate uterus and intravasation of dye in their study from Mumbai.[20] Aggarwal et al.[21] also reviewed the role of HSG and ultrasound in FGTB and observed them to be the best to detect tubercular changes in fallopian tubes and uterus.[21] Thangappah et al.[22] observed classification, distorted uterine cavity, beaded tubes, blocked tubes using intravasation of dye and hydrosalpinx in their recent study on HSG in FGTB.[22] However, HSG has its limitations as certain finding such as hydrosalpinx and hydrosalpinx are non-specific and can occur in other infectious diseases necessitating other tests such as endometrial biopsy and CRS for diagnosis of FGTB.


   Conclusion Top


HSG appears to be a useful modality in detection of FGTB as it gives useful information about uterine and tubal findings without any adverse effects.
